The federal organization charged with monitoring illegal workplace discrimination is called the equal employment opportunity commission (EEOC).
When you are applying for a job or working for a company it is illegal for them to not pick you of something based on what you look like or your gender, nationality and the characteristics that make you, you. Each person regardless of what they look like have to be treated the same and given equal employment opportunity. If there is known discrimination in the workplace, there is a hotline that employees can call to report their workplace to the EEOC.
